Application filed Februaryfi, 1911. Serial No. 607,210.

To all whom it may concern Be it known that I, T EODORE L. Nico- MANN, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Paper Boxes, of which the following is a specification.

My invention relates to an improvement in cardboard boxes of collapsible form.

One of the objects of my invention is to provide a collapsible cardboard box, in which the sides fold inward and in which two opposim sides are scored and slit so that portions of each thereof fold upon one another to permit the remainder sides of the box to overlap each otherin lmock down position.

Another object of my invention is to provide a collapsible box with inwardly folding sides, with two of the opposing sides scored and slit to permit overlapping of the remainder sides into collapsed form, with re inforcing means adapted to overlap the slit portion of said slides for supporting the same in set up position.

Another object of my invention is to provide simple and convenient means for securing a tape or cord to the sides of the box in a secure and reenforced manner without requiring additional features other than employed in the production of my improved box.

The features of the invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which Figure 1 is a perspective view of my box in set up position. Fig. 2 is a central vertical section through the box taken through the sides divided by scored lines and slits, to provide overlapping portions thereof. Fig. 3 is an enlarged detail sectional view of a portion of the sides. Fig. 4 is a top plan view of the box partially collapsed. Fig. 5 is a detail side elevation of the medial upper portion of one of the scored sides.

I am aware that rectangular collapsible boxes with the sides adapted to fold inwardly have been heretofore manufactured, but in such instances, the sides did not equal in area one-half the area of the base, or of such size that two opposing sides overlap each other. With my improved box, the combined area of the opposing sides is greater than the base to enable the formation of a deep box irrespective of its width.

1 represents the base of the box; 2, 3, two opposite rigid sides adapted to remain flat when thehox is either set up or knocked down. 4, represent the other two sides ofa rectangular box, which are divided from the base by scored lines. The sides 4, 5, carry corner-flaps 6which are secured to the sides 2, 3, in any usual manner.

In order to distinguish the sides 4, 5, from the unscored sides 2, S, I term the same divisional sides for the reason that they are provided with the oblique scored lines 7, 8, running diagonally from the respective base corners toward the medial upper edge of the sides, so as to divide said sides 4, 5, into triangular divisions, a, b, 0, when folded.

9, 10, represent curved slits commencing at the terminals of the scored lines 7, 8, and extending outward toward the edge of said sides. The slits determine the contiguity of the divisional folds along the diagonal lines toward the medial portion of the sides, and allow the rigid sides to engage into such slits, providing a clearance, and allow the divisions to overlap the rigid sides.

11 represents a U-shaped reinforcing strip secured to the intermediate section of the sides, preferably by staples 12, 13, and with the inner portion of said strip preferably of greater area or size than the outer limb. and with the edges preferably rounded. This reinforcing strip overlaps the slits to maintain the sides in a rigid vertical position when the box is set up.

14 represents a tape or string serving as a tie for the cover of the box, and it is preferably secured in position, as follows In each of the intermediate portions or divisions of the sides 4, 5, is cut a vertical slit 15, see Fig. 5, through which a tape is passed and knotted at one end. The tape is adapted to project between the outside limb of said reinforcing strip and said intermediate section, and preferably between the staples securing said reinforcing strip. This forms a convenient method of securing the tape in position, and as the slit edges are maintained against distortion relative to each other by the reinforcing strip, the tape is securely held in position.

To fold the box to its knock down position, the reinforcing strip is of such size and out, that by pressing the sectional foldoperation, reference is had to Fig. 4. This view shows the sides a, 5, folded inward, with the reinforcing strip 11 disengaged from the triangular sections. The left hand side, or the right, as desired, is pressed down in advance of the other so as to over:

lap each other, whence the side 3 is folded so as to come beneath the slit edge of the sections Z) of the sides 4:, 5, and the opposite side 2 with the sections 6 overlapping the side 3.

Having described w my invention, claim:

1. A collapsible box having two opposing non-scored sides, two opposing scored and slitted sides, each subdivided by two diagonal scored lines extending from the base corners toward each other terminating at points short of their intersection and continuing with diverging slitted lines to the upper edge, said slits determining the contiguity of the folds when'overlapping the end divisions of a side upon the exterior surface of the intermediate division, and provide clgarancefor the reception of a non-scored s1 e.

2. A collapsible box having two opposing non-scored sides, two opposing scored and slitted sides each-subdivided by two diagonal scored lines extending from the base corners toward each other terminating at points short of their intersection and continuing with diverging slitted lines to the side upper edge, said slits determining the contiguity of the folds when overlapping the end divisions of a side upon the exterior surface of the intermediate division and provide clearance for the reception of a non- I scored sidefand'amarginal strip for each scored side overlapping both faces thereof for-maintaining the rigidity of the sides when non-folded.

In testimonywhereof, I have hereunto set my hand.
